Antminer (120mm computer fan) to 120mm air ducting adapter

Air ducting adapter for 120mm fans to 120mm air ducting. I modified this from the original file to use with the Bitmain Antminers pushing out 40-50C hot air 24/7. So far I have had no issues printing with PLA. This is also compatible with large 120mm computer fans and could be used in conjunction with an extractor fan on a 3d printing system or the like.
